Fruit and Vegetable Physics

My score is abissmal but I laughed the whole way.

I've read Question #5 several times now, and I'm still confused. If she loaded one refrigerator onto her spaceship, then she must have left one refrigerator at home. So which answer should I have chosen? To me, the correct answer is the one she left in her house, but since there was also an answer that said the one in the () refrigerator, that means there are two answers saying the same thing. I also believe, given the high water content of most fruits, that you would have to show me that density is the most important factor in a fruit sinking in water. I tend to think the drag coefficient would have a much higher impact on the fruits mentioned in Question 6.
